Structure for PFBr4 and tell the point group
« on: March 07, 2005, 03:17:20 AM »

My question is:

Predict the structure for PFBr4 and tell what the point group is?

I believe the structure is trigonal bipyramidal but do not know the point group.

Can someone please *delete me*!!!!

Thanks

How many rotations can you do?

It just states to predict the structure for PFBr4 and tell the point group?

rotations = no limit I guess.

I thought it was tbp with Cs point group, but I can't be for sure.

Any Ideas?

Hmmm, If you didn't understand my question then you actually need to read your Inorganic book. It should have a section on point groups. We're here to help if something doesn't make sense, but it sounds like your lacking some fundamentals.

on the principle axis?

Is the F equitorial or axial?

F is always in the axial position isn't it.
